The history of Yeay Mao is unclear, being composed of several legends and interpretations. There are many popular stories surrounding her. It is said that she was a beautiful lady married to a powerful warrior. When he died, she took control of the armies against the Thai and became a celebrity. The story is placed sometime before the French Colony. Another version says that Yeay Mao was the wife of Ta Krohom-Koh - literally "Grandpa Red Neck". They lived in the forest near Pech Nil Mountain. Once they went around and they met a tiger. Ta Krohom-Koh abandoned his wife and the tiger devoured her. Since then, any traveller who passed by the place of the accident, paid respect to her spirit to avoid a similar fate. When they built the highway between Phnom Penh and the sea in what is today Sihanoukville, a small temple was built at the spot. The road was finished by the French in 1876, a fact that increased the pilgrimage to the temple. It included Vietnamese and Chinese believers.
Celebration
The main feast is celebrated in June. The believers go to the Temple or any place destined for the veneration, to bring sacred food, especially pig head, chicken soup, the sla-thoa - a coconut adorned with flowers and leaves and used in religious celebrations in Cambodia, the bay-sei - section of banana tree trunk with legs to which three to nine layers of banana leaves rolled up in finger shape have been attached. It is used also in certain ceremonies. The place of the veneration must be set with three statues:
Yeay Sau : A female spirit, that is the wife of Ung, the kaporal thnol, guard of the paths.
Ta Snong Long : "Grandpa Snong Long", considered the son of Yeay Sau and Ung.
Long Mao: She is the same "Yeay Mao".
Beliefs
According to Seik Sopat and Sadang Tuo, the story of Yeay Mao dates from 1866, when she was a spirit of cruelty that attacked any traveller that did not pay respects to her at Pech Nil Mountain. If the person to whom the spirit sent strong pains because ignoring to pay veneration to her, repented, that person was healed. But if that person did not repent, he or she could die. It was also believed that if a person presented his offering asking to hurt an enemy, the spirit used to fulfil the wish. In 1900, the French army destroyed the first temple and the divinity came in decadence. During the short Japanese invasion of Cambodia in 1940, the army of that country gathered the farmers of Kampot Province and Vietnamese, Chinese and Cham Cambodians, to dig trenches at the ancient sacred place. According to the legend, the workers desecrated the site, bringing the fury of the spirit. People started to suffer epidemics and many died. They explained these epidemics as the fury of Yeay Mao. In order to placate the spirit, the people started again to offer gifts to Yeay Mao and the veneration revived. After the villages near to Pech Nil Mountain, pray to the divinity asking for health and protection. If there was, for example, a theft, they pray to the spirit to punish the criminal.
